AlecTaylor, Can you please clarify what do you mean by SideBar, usually Side bar is commonly considered as a Desktop widget on right side which can hose several other widget like calendar, weather ,close, notes etc, This comes by default with Windows Vista (atleast) and Google also has sidebar if you download Google Desktop search.
By any chance do you want to do that?? Is this possible for you to attach some kind of immage which can give us some clear picture what exactly are you referring to.
